The vertex form of a quadratic equation is used to easily identify the minimum or maximum point of a parabola known as the vertex. We can use vertex form to graph a parabola.

This lesson will show us how to solve a quadratic equation by graphing. Through definitions, illustrations, and applications, we will learn the steps involved in this process.

The formula to find the line of symmetry of a quadratic function is x=-b/2a, where a and b are determined from the standard form ax^2 + bx + c = 0.

The first method is to look at a graph and find these values. The second method requires using a quadratic function, where algebra techniques are used to determine the minimum value.

How do you find the equation of a parabola in intercept form? Consider a parabola given by y = ax^2 + bx + c. Apply the quadratic formula, which gives the roots p and q.
